A highly convergent total synthesis of the potent polyketide macrolide rhizopodin has been achieved in 29 steps by employing a concise strategy that exploits the molecule′s C2 symmetry. Notable features of this convergent approach include a rapid assembly of the macrocycle through a site‐directed sequential cross‐coupling strategy and the bidirectional attachment of the side chains by means of Hor
通过采用利用分子的C 2对称性的简洁策略,已在29个步骤中实现了强聚合的大酮化合物大环内酯大根内酯的高度收敛的全合成。这种收敛方法的显着特点包括通过定点顺序交叉偶联策略快速组装大环,以及通过Horner-Wadsworth-Emmons(HWE)偶联反应实现侧链的双向连接。在此过程中,开发了可扩展的路线,用于合成三个复杂程度相近的主要构件,从而实现了其立体控制构造。该模块化途径将适合于根瘤菌素其他类似物的合成的开发。
